Marechal Star-Delta Motor Connectors – 7 Pole Connectors & Load Break Switches (30A-50A)
Marechal Star-Delta motor connectors have current ratings from 30A to 50A with the ability to connect motors with two operating speeds and a maximum voltages of 415-500V.
Star-Delta motor connectors allow you to connect and disconnect the motors safely thanks to the ability to withstand high overloads without over-heating or affecting performance. When a motor starts, the short-time overload generated is many times greater than the nominal current.
